I've had my REX2000/5 for a few weeks now. The quality on them is really good! The sound and feel of the bass are fantastic, my only gripe is that there were some slight dings in the finish that you could see if you caught them in the light at the right angle!

Compared to my NS-5CR the only real issue weer the dings in the finish - a guitar tech friend of mine has told me that this is just due to the finishing process, the ding is caused by over polishing in that area!

If your looking for a good sounding/playing/looking bass guitar then look no further. Mine has even survived a car crash!!( The bass and I walked, the car and bass case were written off!!)

I quite enjoy my Spector NS2000Q5, as I'll state again and again. I lucked out, I bought it used from a friend who had it in pretty good condition (it's also my first and currently my only bass). I just needed to clean the electronics.

Of course, if you've got the money to spare, I'd say get the /5 instead of the Q5.
